  • HOST: Life in the Sonoran is full of surprises.

  • It rains in the summer, sometimes

  • violently, making it just wet enough to sustain

  • a semi-arid version of the Midwestern grasslands.

  • And with grasslands come the US's most iconic

  • grass cutter, the prairie dog.

  • [music playing]

  • Prairie dogs are, of course, not dogs at all,

  • but are in fact closely related to ground squirrels.

  • Old-timers named them for their dog-like bark.

  • [yip]

  • That's no simple yip.

  • Scientists currently believe that prairie dogs--

  • [yipping]

  • --have the most sophisticated vocal animal

  • language ever decoded.

  • [music playing]

  • They needed to warn each other.

  • [yipping]

  • Because in the Sonoran, of a lot of things like to eat them,

  • including the badger.

  • [music playing]

  • They dig a complex system of burrows.

  • But most mornings, they have to leave to harvest grass.

  • It's a risky time.

  • So while one feeds, another will keep a look out.

  • It takes a very social animal to be this co-operative.

  • They groom each other a bit like monkeys do.

  • And young prairie dogs love to play fight.

  • [music playing]

  • The center of prairie dog life is

  • the family, ruled by a dominant male with a few females.

  • Families can live in large neighborhoods of thousands.

  • Even as organized as they are, it's still

  • tough to be a prairie dog.

  • Only half live past their first year.
